Chronic Obstructive Pulmonary Disease (COPD) affects millions of Americans and often makes breathing difficult, especially during daily activities. For many individuals, oxygen therapy becomes an essential part of managing symptoms and improving quality of life. Oxygen concentrators—devices that filter and provide purified oxygen—are among the most commonly prescribed treatments for COPD.
The good news: Medicare may cover the cost of oxygen concentrators for eligible patients. This guide explains how coverage works, what types of equipment are included, and how to qualify.
What Is an Oxygen Concentrator?
An oxygen concentrator is a medical device that takes air from the surrounding environment, filters it, and delivers oxygen-rich air to the user through a mask or nasal cannula. Unlike oxygen tanks, concentrators do not require refills—they run continuously as long as they’re powered.
There are two main types:
- Stationary (home) concentrators – Larger units for home use, typically delivering higher flow rates.
- Portable oxygen concentrators (POCs) – Lightweight devices designed for mobility, allowing users to travel, shop, and stay active.
Both types may be covered by Medicare when medically necessary.
Does Medicare Cover Oxygen for COPD?
Yes. Medicare Part B covers oxygen therapy—including oxygen concentrators—when specific medical requirements are met. Coverage includes:
- Oxygen concentrators
- Portable oxygen equipment
- Tubing, masks, and related supplies
- Maintenance and servicing by the equipment provider
However, Medicare does not purchase the equipment outright. Instead, it works through a monthly rental system with durable medical equipment (DME) suppliers.
Eligibility Requirements for Medicare Coverage
To qualify for an oxygen concentrator through Medicare, you must meet all the following:
1. You have a COPD diagnosis or another qualifying lung condition
COPD diagnoses may include chronic bronchitis, emphysema, or severe airflow obstruction.
2. Your doctor documents medical necessity
Your physician must state that oxygen therapy is required to manage your condition.
3. You undergo a blood gas test or pulse oximetry exam
Medicare requires proof such as:
- Low blood oxygen levels
- Hypoxemia confirmed through testing
- Documented symptoms related to respiratory impairment
4. You receive the prescription from a Medicare-enrolled doctor
The prescription must specify:
- Flow rate (e.g., 2 liters per minute)
- Frequency and duration of use
- Whether portable oxygen is required
5. You rent equipment from a Medicare-approved DME supplier
Only suppliers that participate in Medicare can bill the program.
What Medicare Covers and What You Pay
Under Medicare Part B:
- Medicare pays 80% of the approved amount
- You pay 20% (after meeting your Part B deductible)
The supplier provides the equipment through a 5-year rental agreement, which includes:
- Delivery and setup
- Routine maintenance
- Replacement supplies (tubes, cannulas, filters)
- 24/7 support for equipment issues
Portable oxygen may also be included if your doctor states you need it to remain mobile.
Types of Oxygen Concentrators Commonly Covered
While Medicare does not guarantee specific brands, it commonly covers:
- Home oxygen concentrators with continuous flow
- Portable concentrators (depending on medical necessity)
- Battery packs for portable devices
- Humidifiers and related accessories
Suppliers usually provide models that meet Medicare’s standards for durability and performance.
How to Get a Medicare-Covered Oxygen Concentrator
1. Visit your doctor
Discuss your COPD symptoms and request testing for oxygen qualification.
2. Complete Medicare-approved testing
This may include arterial blood gas measurement or pulse oximetry.
3. Obtain a prescription
Ensure your doctor includes detailed instructions on your oxygen needs.
4. Contact a Medicare-approved DME supplier
They will review your documentation and handle billing.
5. Receive your equipment
Suppliers set up the device, teach you how to use it, and provide ongoing support.
Improving Daily Life with Medicare-Covered Oxygen
For people living with COPD, an oxygen concentrator can make everyday activities easier, improve sleep, reduce fatigue, and enhance overall quality of life. Medicare’s coverage helps ensure patients receive reliable equipment without overwhelming costs. With the right prescription, proper documentation, and a Medicare-approved supplier, you can access the oxygen support you need to breathe easier.
